Description

Technical Field

[0001] This utility model relates to the field of foundry waste sand pretreatment technology, and in particular to a foundry waste sand pretreatment device. Background Technology

[0002] As one of the main solid wastes in the sand casting industry, the pretreatment of foundry waste sand is a key preliminary step to achieve resource recycling and environmentally friendly disposal. This process removes impurities such as metal slag and binder residue from the waste sand and adjusts the physical and chemical properties of the sand, such as particle size distribution and moisture content. This provides a basic guarantee for the subsequent reuse of recycled sand or safe disposal that meets environmental standards, and is of great significance for alleviating the shortage of natural sand resources and reducing solid waste pollution. In the current pretreatment process of foundry waste sand, the vibrating screen is one of the core equipment for achieving sand classification and impurity separation. However, during the generation and storage of foundry waste sand, it is easy to form agglomerates due to factors such as fluctuations in moisture content and the stickiness of residual binders. These agglomerates are difficult to disperse effectively when passing through the vibrating screen, which not only leads to screen blockage and reduces screening efficiency and classification accuracy, but also causes some qualified sand particles to be trapped by the agglomerates and cannot be effectively separated. This affects the quality and economy of subsequent waste sand recycling, becoming a key issue restricting the optimization of foundry waste sand pretreatment process. Therefore, this application provides a pretreatment device for foundry waste sand to meet the requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pretreatment device for foundry waste sand, which solves the technical problem that waste sand agglomerates are not easy to screen.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pretreatment device for foundry waste sand includes: a vibrating screen device, a support mounted on the vibrating screen device, an mounting rod mounted on the support, and a hopper mounted on the mounting rod; The support frame is equipped with a material feeding structure; The support is provided with a dispersion structure, which includes a first drive motor, a first shaft is installed at the output end of the first drive motor, a rotating rod is installed on the first shaft, and a vibration spring is installed on the rotating rod.

[0005] The silo and mounting rod are fixed by a bracket. The silo is used to store foundry waste sand to be processed. The discharge structure controls the discharge volume of the silo. In the dispersion structure, the first drive motor drives the first shaft and rotating rod to rotate. The vibration spring on the rotating rod generates high-frequency vibration and mechanical impact as it rotates. When the waste sand enters the silo, the vibration spring can break up the agglomerated sand clumps, so that the waste sand enters the vibrating screen in a dispersed state, thereby improving the screening efficiency. The pre-dispersion of agglomerated waste sand by the vibration spring of the dispersion structure solves the problem of screening difficulties caused by sand agglomeration in traditional vibrating screens.

[0006] Optionally, the vibrating screening device is equipped with a smooth surface extension groove, which is located directly below the material outlet of the hopper; the support is provided with a guide component.

[0007] The smooth-surface extension trough receives waste sand falling from the silo, and the smooth surface reduces waste sand retention.

[0008] Optionally, a fixing frame is welded onto the bracket, and the first drive motor is mounted on the fixing frame.

[0009] The fixed frame is used to support and fix the first drive motor.

[0010] Optionally, the material discharge structure includes an electric telescopic rod, the telescopic end of which is equipped with a baffle, the top of which is in contact with the discharge port of the hopper.

[0011] The opening and closing degree of the baffle is controlled by the extension and retraction of the electric telescopic rod, thereby adjusting the discharge speed and flow rate of the hopper.

[0012] Optionally, a support rod is mounted on the bracket, and the electric telescopic rod is mounted on the support rod.

[0013] The support rod is used to support and fix the electric telescopic pole.

[0014] Optionally, the guiding component includes a second drive motor, the output end of which is equipped with a second shaft, and a toggle plate is mounted on the second shaft. The toggle plate is 15 cm away from the inner bottom wall of the smooth surface extension groove.

[0015] In the guiding assembly, the second drive motor drives the second shaft and the actuating plate to rotate. The actuating plate maintains a distance from the bottom wall of the smooth extension trough. When the waste sand is conveyed on the extension trough, the actuating plate performs secondary dispersion and guidance on the sand, further guiding the waste sand to the vibrating screen for screening.

[0016] Optionally, a connecting rod is mounted on the bracket, and the second drive motor is mounted on the connecting rod.

[0017] The connecting rod is used to support and fix the second drive motor.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects: By setting up a dispersion structure and starting the first drive motor, the vibration spring is driven to rotate. The vibration spring generates high-frequency vibration and mechanical impact as it rotates. When the waste sand falls from the hopper, the vibration spring can break up the agglomerated sand clumps, allowing the waste sand to enter the vibrating screening device in a dispersed state, thereby improving screening efficiency and achieving the purpose of breaking up the agglomerated waste sand. The waste sand falling from the silo is received by the smooth surface extension trough. The smooth surface reduces the retention of waste sand and reduces the adhesion and blockage of waste sand during the conveying process. By setting up the guiding component, the second drive motor is started, which drives the actuating plate to rotate slowly, thereby dispersing and guiding the waste sand falling on the surface of the smooth surface extension trough, and further guiding the waste sand to the vibrating screen for screening.

The vibration spring 605 generates high-frequency vibration and mechanical impact as it rotates. When the waste sand falls from the hopper 4, the vibration spring 605 can break up the agglomerated sand clumps, so that the waste sand enters the vibrating screening device 1 in a dispersed state, thereby improving the screening efficiency and achieving the purpose of breaking up the agglomerated waste sand.

The smooth surface extension groove 101 is made of 304 stainless steel and the surface is polished smooth. The smooth surface extension groove 101 receives the waste sand falling from the hopper 4. The smooth surface reduces the retention of waste sand and reduces the adhesion and blockage of waste sand during the conveying process. A guide assembly 7 is provided on the support 2. The guide assembly 7 includes a second drive motor 702. A second shaft 703 is installed at the output end of the second drive motor 702. A toggle plate 704 is installed on the second shaft 703.

The vibration spring 605 generates high-frequency vibration and mechanical impact as it rotates. When the waste sand falls from the hopper 4, the vibration spring 605 can break up the agglomerated sand clumps, so that the waste sand enters the vibrating screening device 1 in a dispersed state, thereby improving the screening efficiency and achieving the purpose of breaking up the agglomerated waste sand. The smooth surface extension trough 101 receives waste sand falling from the hopper 4. The smooth surface reduces waste sand retention and reduces adhesion and blockage during the conveying process. In addition, by starting the second drive motor 702, it drives the second shaft 703 to rotate. The rotation of the second shaft 703 drives the slow rotation of the actuating plate 704, thereby dispersing and guiding the waste sand falling on the surface of the smooth surface extension trough 101, and further guiding the waste sand to the vibrating screen 1 for screening.
